The Memory Neutralizing Chip is a chip installed in the brains of the Dark Legionnaires upon their birth or joining the Dark Legion. When activated, it wipes the subject's memories. Julie-Su is the only Legionnaire confirmed to have been affected by hers, as it was used to make her unaware of her relation to GrandmasterLuger and her step-siblings, Kragok and Lien-Da (thinking she'd be an obstacle in their pursuit of power), and then to forget her adoptive parents when it was feared they'd reveal the truth of her family to her.
